1.	The equilibrium for the synthesis of ammonia isN2 + 3H2 \(\rightleftharpoons\) NH3 + xkJWhat is the effect of pressure, temperature and concentration on this equilibrium ?
Answer» Effect of pressure : High pressure favours the formation of ammonia. An increase in pressure will favour the reaction that decreases the number of gas molecules. The equilibrium will shift to the right and the yield of ammoina will be increased. Effect of temperature: Low temperature favours the formation of ammonia, a decrease in temperature favours the exothermic reaction because it releases energy, it will favour the forward reaction and the yield of ammonia will be increased. Effect of concentration: High concentration of reactants favours the formation of ammonia, According to Le-Chatelier’s principle, if the concentration of N₂ or H₂ is increased then equilibrium will shift to forward direction and the yield of ammonia will be increased.
